Yagi – antenna
The yagi antenna or yagi-Uda antenna is a high frequency antenna which is used to receive TV signals in very high (VHF) frequency range. It is commonly used in communication when a frequency is above 10MHZ. The
Field effect transistor (FET)
What is mean by FET? FET stands for Field Effect Transistor. The FET is a three terminal unipolar solid state device in which the current is by an electric field as in vacuum tubes. Vacuum tubes are
Satellite communication
What is a satellite communication? A satellite communication is microwave repeater. In satellite communications, signal transferring between the sender and receiver is done with the help of satellite. Collect the information from different sources earth station
Types of bipolar junction transistor
There are two types of Bipolar Junction Transistor (BJT) are given below; NPN bipolar junction transistor. PNP bipolar junction transistor. NPN Bipolar Junction Transistor In NPN transistor the current is conducted by the electrons as majority charge
Specification of transistor
There are many specification of transistor,some of below: Collector-base voltage (VCB) is the maximum voltage that can be applied across the base and collector of a transistor. Collector-emitter voltage (VCEO) is the maximum that can be applied
RADAR System
RADAR is stands for Radio Detection And Ranging. RADAR system operates in microwave frequencies range. In RADAR system high frequency and high power sinusoidal signals is transmitted. If there is any target then the reflected signals is
Light emitting diode(LED)
The LED stands for a light emitting diode is an optical semiconductor device which emits lights when voltage is applied and it convert the electrical energy into light energy. Just like a p-n junction that can absorb
Difference between PN junction diode and zener diode
Following are the difference between PN junction diode and zener diode: PN junction diode Zener diode PN junction is not properly doped to control reverse breakdown. Zener diode is properly doped to control reverse breakdown. PN junction
Difference between LED and photodiode
LED photodiode It has a light emitting diode. It has a light detecting device. The LED converts electrical energy into light energy. The photodiode converts light energy into electrical energy. Due to the recombination of electrons and
Following are the difference between waveguide and transmission line
Waveguide Transmission Line The waveguide is a hollow metallic structure through which electric and magnetic fields are transmitted. The transmission line is a conductor which is used to carry electrical signal over a long range. It has
